Abstract: Devices for the discharge of bodily waste, in particular for the soiling-free discharge of bodily waste from a person situated on a bed or a seat. A bed's mattress (2) is provided with a slot (4) that may be opened and closed, and which extends continuously through the thickness of the mattress (2). The slot is controllably openable and closable via an actuated mechanism. Hygienic elimination of bodily waste while lying down or sitting may be achieved with little effort.

Abstract: A turbine, in particular for harvesting energy in flowing air or flowing water, is easily adaptable to different application conditions and facilitating a comparably high degree of efficiency. This is achieved in that the basic shape of the turbine is cylindrical and is provided with blades which are parallel to an axis of the turbine. The blades are pivotally arranged in joints on the outer circumference of at least one turbine wheel. The blades are substantially L-shaped. The longer limb of the blade is curved preferably in a manner corresponding to the radius of the turbine casing, and the shorter limb lies within the surface line of the turbine.

Abstract: A wheelchair has an additional auxiliary drive device that allows the wheelchair to be moved even without using one's hands. Two drive wheels are connected by means of a wheel hub and one wheel is arranged at one side of a wheelchair frame and the other wheel at the opposite side of the wheelchair frame. A seat is arranged between the drive wheels, the seat surface of which is arranged such that it can be tilted along the wheel axis of the drive wheels, wherein the tilting axis of the seat is located centrally between the drive wheels above the wheel axis.

A seat is arranged between the drive wheels, the seat surface of which is arranged such that it can be tilted along the wheel axis of the drive wheels, wherein the tilting axis of the seat is located centrally between the drive wheels above the wheel axis.

Abstract: A water turbine for producing energy in flowing water systems, which can be easily adapted to different usage conditions and enables comparatively high efficiency. The turbine has blades that are pivotably disposed between turbine wheels by joints on the outside circumference of the turbine wheels. An inflatable element is disposed on at least one of the blades and extends parallel to the axis of rotation of the wheels.
